I've been finding Carbon 6 quality to be going down hill a bit. Chambered up a 6 Creedmoor with a shorty carbon wrapped carbon 6 and it shot all over the place. Went to a Proof Research and re-barreled the set up and shot great, figured it was a crappy barrel. Now I have 2 well know shops that will not even chamber a set up using Carbon 6. What are you guys finding at this point? My preferences normally run Bartlein or Benchmark for carbon barrels, Proofs and Carbon 6 were 2nd choices.
